ラズパイやArduinoでセンサーなどを使うときにI2C通信がよく使われています。この場合、ラズパイやArduinoがマスターで、センサーがスレーブになって、マスターからスレーブのデータを書き込んだり、データを読み出したりします。 センサーなどの代わりに ...

LiquidCrystal_I2C lcd(0x27, 16, 2); // run ic2_scanner sketch and get the IC2 address, which is 0x3f in my case,it could be 0x3f in many cases // initialize the library by associating any needed LCD ...

秋月電子で購入したBOSCH社製9軸センサ「BNO055」を実装したセンサーフュージョンモジュール「AE-BNO055-BO」を使用し、「Arduino UNO R4 MINIMA」とI2C通信を行いました。が、動作確認できるまでに少々苦労したので備忘録としてまとめました。 下記が回路構成です。

An I2C slave project built on top of the Wire.h library. Designed to easily drop into a variety of projects which can then be managed by an I2C master. This project uses a combination of an in-memory ...

The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...

In this project, we have the above mentioned components and the working is quite east to understand .The input will be taken from the user through the matrix keypad. At first we have to give The Hour ...
